Description

technical field [0001] The invention relates to the technical field of material processing and forming, in particular to an electromagnetic forming system and a forming method of a terminal. Background technique [0002] With the increasing complexity of modern industrial systems and the introduction of a large number of electronic and electrical equipment, the number of wire harnesses has increased significantly. The so-called wire bundle refers to a single solid conductor or twisted conductor wrapped in the same insulating material, which is used to transmit current or electrical signals in the circuit, and the terminal plays a decisive role in the reliable connection of the wire bundle. The two most commonly used terminal connection methods are soldering and crimping. [0003] The traditional soldering process has wide adaptability and can adapt to different requirements and batch production. But at the same time, there are also defects that are difficult to solve, such...

Problems solved by technology

However, the crimp connection still has the following disadvantages: the tightness of the core wires after crimping is not high, and there are always a few core wires that are loose, which increases the contact resistance of the joint; Force and tightening, poor uniformity, which in turn reduces the mechanical tensile and torsional resistance of the joint

If the electromagnetic forming terminal is used, the unevenness of the deformation will be caused due to the unevenness of the magnetic field force and the insufficient rigidity of the core material.
